  • Improving Silvofishery Management Through Seedling Growth – Environment
           Quality Dynamic Relation Analysis

    • Authors: Endah Dwi Hastuti, Rini Budi Hastuti
      Abstract: Mangrove plants are sensitive to environment condition. This research aimed to analyze the linkages of mangrove growth and environment dynamics and to estimate the growth of mangrove along with the environment dynamics. The research was conducted through the field experiment by the plantation of A. marina in silvofishery pond canals. Data collection was conducted for 18 months with 3 months observation interval. The environment variables observed including temperature, salinity, turbidity, pH, dissolved oxygen, TSS, sediment organic matter, nitrogen and phosphorus, and the growth of mangrove seedling. Analysis was conducted through regression and modelling with Powersim software. The result showed that the height growth was affected by dissolved oxygen, temperature, salinity, turbidity and pH, while the diameter growth was affected by TSS concentration. Inversely, the growth of mangrove also had a significant effect on temperature, change of organic matter and nutrient sediment concentration. Simulation showed that the height and diameter growth rates of A. marina seedling were dynamically changed among periods. Simulated seedling growth for one year forecast resulted in the rate of 0.115024 to 0.282294 cm/day for height and 0.001287 to 0.006031 cm/day for diameter. The simulation also indicated the continuous accumulation of organic matter and nitrogen over time. This research concluded that under limited environment dynamic, the growth of mangrove could be estimated. This model is a novelty in ecological studies. This research might initiates the more advanced ecological studies. Systematic estimation of ecosystem behaviour could be applied to formulate the best management practices, particularly in the silvofishery activities.

  • In Vitro Callus Induction from Leaf Explants of Vanda sp Stimulated by

    • Authors: Nurul Amalia, Iman Budisantoso, Kamsinah Kamsinah
      Abstract: The addition of growth regulator is one of the critical success factors in in vitro cultures. 2,4-D as a plant regulator in media can stimulate the cell division, enlargement of the explants and promotes the formation and growth of callus. The purpose of this study was to determine the time of callus formation and to determine the best concentration of 2.4-D in inducing the growth of callus from leaf explants of Vanda sp. This research was conducted by experiment with completely randomized design, which consists of six levels of treatment concentration of 2,4-D i.e. 0 ppm; 1 ppm; 1.5 ppm; 2 ppm; 2.5 ppm; and 3 ppm. The parameters observed were the percentage of callus formation and the form of callus from Vanda sp leaf explants. The results were statistically analyzed by using MINITAB program version 17. Analysis of variance (ANOVA) was performed and the difference between means score/value was separated by F test at p < 0.05. The results showed that 2,4-D treatment give significant effect (F 5,12 = 3,20; p = 0,046 < 0,05) on the callus growth time and its percentage. Application of 2 ppm 2.4-D was the best concentration for accelerating the callus growth time (14.3 days after planting) and increasing the percentage of callus formation (83.3%). Most of callus type were proliferative callus (36.11%) and senescence callus (11.11%). The results of this research are very important to grow the callus from Vanda leaves orchid explant because it is very diffucult to grow.

  • Ethnobotany Study to Identify Wood Apple Conservation Efforts as An
           Identity Plant of Rembang Regency Central of Java Province

    • Authors: Enni Suwarsi Rahayu, Nur Kusuma Dewi, Talitha Widiatningrum, Lina Herlina
      Abstract: Feronia limonia (L.) Swingle (wood apple) is an identity plant of Rembang Regency of Central Java Province. However, the  population is very limited. In order to identify the conservation efforts, this ethnobotany study was aimed to determine traditional knowledge on the existence, economic value, utility, breeding technique and conservation of wood apple. The survey was conducted on a total of 102 local people from 10 sub-districts which were determined by proportionally stratified random sampling. Data were collected by questionnaires and individual interviews; then were descriptively analyzed. The results showed that all of respondents knew the figure of wood apple, but only 79.50% understood its status as plant identity. Most of respondents (96%) stated that the fruit  have low economic value, 80.39% respondents have utilized ripe fruit as ingredients of beverages and stems as firewood. This utilization was only equal to 36.85% compared to the potential usability based on research results. The most important outcome was the finding that some respondents thought if conservation efforts should be undertaken, while the others stated unnecessary which was mainly forced by the situation of the frequently roof damage due to falling fruit and the plants’ less economic profit.  It was concluded that the traditional knowledge about the existence, economic value, and breeding technique were good; and on the contrary the knowledge about the usability was bad. Based on the results, it is suggested to educate local people about the importance of woody apple conservation, as well as to inform and train the various uses.

  • The Influence of Environmental Factors on the Diversity of Gastropods in
           Marsegu Island, Maluku

    • Authors: Wiwien Bula, Fredy Leiwakabessy, Dominggus Rumahlatu
      Abstract: Gastropods are known to have a wide distribution. They can live in a variety of habitats and influenced by various environmental factors. The aim of this study was to investigate the diversity of gastropods and its relationship with the physical and chemical environment of a water. This research was an ecological research with correlational descriptive type. The selection of Marsegu Island was based on the fact that the area is a conservation area, both the forest and sea are frequently visited by tourists. The results of this research showed that there were 22 species of gastropod found in the water of Marsegu Island. The most commonly found was from the genus of Cypraea (5 species). Gastropods found mostly from the family of Strombidae which consisted of 4 genera i.e. Lambis, Canarium, Strombus and Lentigo. The value of gastropod diversity in the three research stations was moderate, 2.93, 2.91 and 2.95 respectively. In addition, there is a correlation between environmental factors and the diversity of gastropods. The simultaneous effect of the independent variables toward the dependent variables can be explained by the magnitude of the determination coefficient (R Square) which was 0528 or 52.8%. Result of this study confirms that the environmental factors greatly affects the diversity of Gastropod in the coastal waters of Marsegu island. The results can provide benefits as control over fishing and coastal pollution due to human activities.

  • Molecular Identification of Endophytic Fungi from Bark of Raru
           (Cotylelobium melanoxylon) that Produce the Antibacterial Compounds

    • Authors: Uswatun Hasanah, Riwayati Riwayati, Idramsa Idramsa, Eko Prasetya
      Abstract: The Dipterocarpaceae plant, raru(Cotylelobium melanoxylon) is widespread in Southeast Asia. The bark of raru has been used by local communities in North Sumatera as antidiarrheal drugs due to its antibacterial compounds. The antibacterial activity of the raru’s bark is induced by endophytic fungi that live in the region of the bark. This study aimed to identify the endophytic fungi-producer of antibacterial compounds in the bark of raru (C. melanoxylon) by means of molecular analysis. In general, endophytic fungi have the ability to inhibit the growth of pathogenic bacteria. Thirty-eight isolates of endophytic fungi were isolated from the bark of raru. Selection of isolates for antibacterial activity againstEscherichia coli ATCC 35218 and Staphylococcus aureus ATCC 25923 used the dual culture assay. Selection using the dual culture assay yielded 6 endophytic fungal isolates that have the ability to inhibit the growth of test bacteria. EF10A sample was the most powerful isolate inhibiting the growth of both bacteria test. Those six bacteria molecularly identified used a sequence generated from ITS rDNA region. Based on rDNA ITS region sequences, isolate, the producers of the antibacterial compound were identified as Talaromyces cellulolyticus, Penicillium purpurogenum, Aspergillus sp., Trichoderma harzianum, and Aspergillus orizae. The results of this study can be used by researchers to explore more potential endophytic fungi in raru plants (C. melanoxylon) as a source of medicine. The data obtained need to be supported by further research to isolate the bioactive compounds that can inhibit the growth of microbial pathogens.

  • Screening of Acetic Acid Bacteria from Pineapple Waste for Bacterial
           Cellulose Production using Sago Liquid Waste

    • Authors: Nur Arfa Yanti, Sitti Wirdhana Ahmad, Sri Ambardini, Nurhayani Haji Muhiddin, La Ode Iman Sulaiman
      Abstract: Bacterial cellulose is a biopolymer produced by fermentation process with the help of bacteria. It has numerous applications in industrial sector with its characteristic as a biodegradable and nontoxic compound in nature. The potential application of BC is limited by its production costs, because BC is produced from expensive culture media. The use of cheap carbon and nutrient sources such as sago liquid waste is an interesting strategy to overcome this limitation. The objective of this study was to obtain the AAB strain that capable to produce bacterial cellulose from sago liquid waste. Isolation of AAB strains was conducted using CARR media and the screening of BC production was performed on Hestrin-Schramm (HS) media with glucose as a carbon source. The strains of AAB then were evaluated for their cellulose-producing capability using sago liquid waste as a substrate. Thirteen strains of AAB producing BC were isolated from pineapple waste (pineapple core and peel) and seven of them were capable to produce BC using sago liquid waste substrate. One of the AAB strains produced a relatively high BC, i.e. isolate LKN6. The result of morphological and biochemical test was proven that the bacteria  was Acetobacter xylinum.. The result of this study showed that A. xylinum LKN6 can produce a high yield of BC, therefore this strain is potentially useful for its utilization as a starter in bacterial cellulose production.

  • The Effect of Biofertilizer on The Diversity of N2O Reducing Bacteria in
           Paddy Fields of Sukabumi, Indonesia

    • Authors: Alfan Cahyadi, Iman Rusmana, Nisa Rachmania Mubarik
      Abstract: Some of the methanotrophic bacteria and N2O reducing bacteria have been proven to be able to support the plant growth and increase the productivity of paddy. However effect of the methanotrophic and N2O reducing bacteria application as a biofertilizer to indigenous N2O reducing bacteria is still not well known yet. The aim of this study was to analyze the diversity of N2O reducing  bacteria in lowland paddy soil based on a nosZ gene. Soil samples were taken from lowland paddy soils in Pelabuhan Ratu Sukabumi, West Java, Indonesia. There were two treatments for the paddy field soil, ie. biofertilizer-treated field 20% fertilizer (50 kg/ha) with the addition of biofertilizer and 100% fertilizer. PCR amplification of nosZ gene was successfully conducted using nosZF and nosZR primer pair. Denaturing Gradient Gel Electrophoresis (DGGE) process was conducted at 150 V for 5.5h. There were three differences nosZ bands were sequenced. The phylogenetic analysis showed that they were close to uncultured bacteria. Microbial diversity in the biofertilizer-treated field was higher than that of  in the 100% fertilizer-treated field. The biofertilizer treatment has higher in microbial diversity than that of applied non-biofertilizer paddy fields. This research might have impact in the application of biofertilizers due to the emission of N2O as a green house gas from paddy fields farming activity. The biofertilizer has great potential application in sustainable environmental friendly agriculture systems.

  • Callus Induction of Gendarussa (Justicia gendarussa) by Various
           Concentration of 2,4-D, IBA, and BAP

    • Authors: Dwi Kusuma Wahyuni, Putri Andriani, Arif Nur Muhammad Ansori, Edy Setiti Wida Utami
      Abstract: Justicia gendarussa Burm.f., a medicinal plant, is Acanthaceae that has many functions. Furthermore, the compounds in gendarussa must be produced in high quantity and quality by applying callus culture method. Accordingly, it is important to study the effects of plant growth regulators (2,4-D, IBA, and BAP) on callus induction of gendarussa leaves. This research design utilized a factorial design with two factors (2,4-D and IBA: 0.5, 1, 1.5 mg/L and BAP: 0.5, 1, 1.5, 2 mg/L). The experiment consisted of 24 treatments, each of which was repeated 3 times. Observation was carried out in 6 weeks. Data on the time of callus formation, percentage of explants formed callus, and callus morphology were analyzed descriptively,while data on fresh and dry weight were analyzed by Two-Way ANOVA (α = 0.5). Interestingly, the results showed that various concentration of plant growth regulators (2,4-D, IBA, and BAP) affected callus induction from leaf explants of gendarussa. We concluded that the most optimal treatment combination of concentration of plant growth regulators in inducing callus from leaf explants of gendarussa is 1.5 mg/L 2,4-D and 2 mg/L BAP with a relatively long period of callus formation at the earliest, i.e. on day 5, 2.247 g of fresh weight, 0.108 gof dry weight, white callus translucent, and friable. Moreover, the optimum treatment will be used to produce secondary metabolite and seed synthetic by cell suspension culture.

    • Authors: Imam Widhiono, Eming Sudiana, Edy Yani
      Abstract: Wild bee pollinators (Hymenoptera : Apiade) diversity and abundance were studied in three types of plantation forest on Mt. Slamet (Central Java Province, Indonesia). The aims of the research was to know the diversity and abundance of wild bee pollinators and to determine the possibility of plantation forest contribution on wild bees conservation. Sampling has been done at three stands: a pine forest (PF, with Pinus merkusii), an Agathis forest (AF, with Agathis damara) and a community forest (CF, with Albizia falctaria). Each habitat was divided into 5 line transect (100 x 5 m) and sweep nets were used to collect the wild bee samples. Sampling was done eah month from April to August 2015. The diversity of wild bees was high (12 species in 9 genera; members of the Apidae (7 species were dominant). The most abundant species across the forests were Apis cerana (343 individuals; 25.5% of total), Trigona laeviceps (195 individuals; 14.5%), and Megachille relativa (165 individuals; 12.3%). Measurements of species diversity (H’), species evenness (E), habitat similarity (Ss) and species richness indicated that the wild bee species diversity in the region was relatively high (H’ = 1.275) to (H’ = 1.730); (E= 0.870) to (E = 0.93). The result showed that the diversity of wild bees in three different plantation forest habitats on Mt. Slamet were similar and  can be concluded that plantation forest types were important for pollinator conservation, and an appropriate future preservation strategy should include of the areas of all plantation forest types

  • Genetic Variability of Local Corn Cultivars from Kisar Island Southwest
           Maluku Regency Using Microsatellite Molecular Marker

    • Authors: Hermalina Sinay, Ritha Lusian Karuwal
      Abstract: Kisar Island is one area in Southwest Maluku Regency, that has high diversity of corn germplasm with different morphological characteristic and can be investigated at the molecular level through DNA identification using microsatellite. This research aim was to reveal the genetic variability of local corn cultivars from Kisar Island using microsatellite molecular marker. The use of microstellile markers is based on one reasons that the genetic information is polymorphic, and will be better to identify genetic diversity of plants including corn. Corn cultivars used were obtained from farmer in Kisar Island, and three reference varieties as outgroup were obtained from Institute of Cereals in Maros South Sulawesi. Polymerase chain reaction was conducted following the protocols from Fast Start kit (Qiagen-USA). The data obtained then analyzed with MVSP 3.1A Software for dendogram construction. The results showed that the appearance of DNA bands was vary (monomorphic and polymorphic) for local cultivars as well as reference varieties, with one or two bands on each primer. Based on the dendogram, there are three main clusters with similarity index ranged from 20% -100%. It can be concluded there is very low similarity and disntnat kinship of local cultivars. The novelty of this research is knowing kinship relationship between local corn in Kisar Island which is not known yet. This results is expected to provide benefits regarding the breeding program, and for instance, it can be an important information regarding the development of local corn as a source in assembly the superior corn cultivars.

  • Traditional Knowledge on The Animal Utilization by The Hatam Tribe of
           Manokwari, West Papua Province

    • Authors: Simon Sutarno, Ibnul Qayim, Ignatius Muhadiono, Yohanes Purwanto, Ervizal A. M. Zuhud
      Abstract: Animal utilization in traditional community life is an integral part of traditional knowledge itself. This research aims to reveal the Hatam people’s traditional knowledge about the utilization of animals in their lives. The method used is the exploratory survey method. The respondents were determined purposively using the snowball sampling technique. The results showed that there are at least 55 species of animals commonly used by the Hatam people. Based on the forms of utilization, the animals can be divided into six groups: consumption, traditional medicine, specific meanings, traditional technology and arts, significant value, and traditional purposes. Wild animals are most widely used for the living needs of the Hatam people. The traditional hunt that is limited and the communal land ownership system (ulayat system) practiced by the Hatam people have indirectly helped preserve and ensure the availability of wildlife for the Hatam people’s needs. In addition to being a form of documentation of Hatam people’s traditional knowledge, the results of this research also have significance for the development of science especially in the field of ethnozoology. The form of interaction between Hatam people and animals revealed in this research can also serve as a reference for designing development policies related to the presence of Hatam people in the Arfak mountains.

      Abstract: Okra (Abelmoschus esculentus) is reported to have various biological functions such as antioxidant, anticancer and anti-inflammation. However, few studies has been reported in immunomodulatory activity of okra to prevent disease caused by bacteria infection. In this study, the immunomodulatory activities of polysaccharides from okra (Abelmoschus esculentus) pods were investigated further through spleen weight and B-lymphocytes proliferation in mice infected by Staphylococcus aureus. Okra polysaccharides was obtain by water extraction and ethanol precipitation. Okra polysaccharide with doses of 25, 50, 75 and 100 mg/kg BW was orally administrated to mice with or without Staphylococcus aureus infection. Spleen weight was evaluated among treatment group and control group. B-lymphocytes proliferation was evaluated by MTT assay using LPS induction. Results showed that okra polysaccharide at the doses of 50, 75 and 100 mg/kg increased spleen weight (p < 0,05) significantly. For B-lymphocytes proliferation, 75 and 100 mg/kg of okra polysaccharide significantly improved B-lymphocytes proliferation (p < 0,05). Between the spleen weight and B-lymphocytes proliferation had a positive correlation of 73.3%. These result suggest that okra polysaccharide could improve immune response and utilized as novel candidate of neutraceutical
